We developed a comprehensive workflow for a clinically applicable strategy for NIPGT-A based on next-generation sequencing (NGS) technology. We performed MALBAC whole genome amplification and NGS on spent blastocyst culture media of Day 3 embryos fertilized with intra-cytoplasmic sperm injection (ICSI). Spent embryonic culture media of morphologically good quality score embryos were enrolled in further analysis with the blank culture media as background control. Chromosomal abnormalities were identified by an optimized bioinformatics pipeline applying a copy number variation (CNV) detecting algorithm. We demonstrate a comprehensive workflow covering both wet- and dry-lab procedures supporting a clinically applicable strategy for NIPGT-A. It can be carried out within 48 h which is critical for the same-cycle blastocyst transfer, but also suitable for “freeze all” and “elective frozen embryo” strategies. The described integrated approach of non-invasive evaluation of embryonic DNA content of the culture media can potentially supplement existing pre-implantation genetic screening methods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=next%20generation%20sequencing" title="next generation sequencing">next generation sequencing</a>, <a href="https://publications.waset.org/abstracts/search?q=in%20vitro%20fertilization" title=" in vitro fertilization"> in vitro fertilization</a>, <a href="https://publications.waset.org/abstracts/search?q=embryo%20assessment" title=" embryo assessment"> embryo assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=non-invasive%20pre-implantation%20genetic%20testing" title=" non-invasive pre-implantation genetic testing"> non-invasive pre-implantation genetic testing</a> </p> <a href="https://publications.waset.org/abstracts/143714/non-invasive-pre-implantation-genetic-assessment-using-ngs-in-ivf-clinical-routine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143714.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">156</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">10</span> Post-Harvest Biopreservation of Fruit and Vegetables with Application of Lactobacillus Strains </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Judit%20Perjessy">Judit Perjessy</a>, <a href="https://publications.waset.org/abstracts/search?q=Zsolt%20Zalan"> Zsolt Zalan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ferenc%20Hegyi"> Ferenc Hegyi</a>, <a href="https://publications.waset.org/abstracts/search?q=Eniko%20Horvath-Szanics"> Eniko Horvath-Szanics</a>, <a href="https://publications.waset.org/abstracts/search?q=Krisztina%20Takacs"> Krisztina Takacs</a>, <a href="https://publications.waset.org/abstracts/search?q=Andras%20Nagy"> Andras Nagy</a>, <a href="https://publications.waset.org/abstracts/search?q=Adel%20Klupacs"> Adel Klupacs</a>, <a href="https://publications.waset.org/abstracts/search?q=Erika%20Koppany-Szabo"> Erika Koppany-Szabo</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhirong%20Wang"> Zhirong Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Kaituo%20Wang"> Kaituo Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Muying%20Du"> Muying Du</a>, <a href="https://publications.waset.org/abstracts/search?q=Jianquan%20Kan"> Jianquan Kan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The post-harvest diseases cause great economic losses in the fruit and vegetables; the prevention of these deterioration has great importance. Against the fungi, which cause most of the diseases, are extensively used the fungicides. However, there are increasing consumer concerns over the presence of pesticide residues in food. An alternative and in recent years, increasingly studied method for the prevention of the diseases is biocontrol, where antagonistic microorganisms are used for the control of fungi. The genera of Lactobacillus is well known and extensively studied, but its applicability as biocontrol agents in post-harvest preservation of fruit and vegetables is poorly investigated. However these bacteria can be found on the surface of the plants and have great antimicrobial activity. In our study we have investigated the chitinase activity, the antifungal effect and the applicability of several Lactobacillus strains to select potential biocontrol agents. We investigated the determination of the environmental parameters of a gene (encoding chitinase) expression and we also investigated the relationship between actual antifungal activity and potential chitinase activity. Mixed cultures were also developed to enhance the antifungal activity and determined the optimal mold spore and bacteria concentration ratio for the appropriate efficacy. Five Lactobacillus strains (L. acidophilus N2, L. delbrueckii subsp. bulgaricus B397, L. sp. 2231, L. sake subsp. sake 2471, L. buchneri 1145) possess chitinase-coding gene from the 43 investigated Lactobacillus strains. Proteins with similar molecular weight and separation properties like bacterial chitinases were detected from these strains, which also possess chitin-binding property. Nevertheless, they were inactive, lacks the chitinolytic activity. In point of the cumulative activity of inhibition, our results showed that certain strains were statistically significant in a positive direction compared to other strains, e.g., L. rhamnosus VT1 and L. Casey 154 have shown great general antifungal effect against 11 molds from the genera Penicillium and Botrytis and isolated from spoiled fruit and vegetables. Also, some mixed cultures (L. rhamnosus VT1 - L. Plantarum 299v) showed significant antifungal effects against the indigenous molds on the surface of apple fruit during the industrial storage experiment. Thus, they could be promising for post-harvest biopreservation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biocontrol" title="biocontrol">biocontrol</a>, <a href="https://publications.waset.org/abstracts/search?q=chitinase" title=" chitinase"> chitinase</a>, <a href="https://publications.waset.org/abstracts/search?q=Lactobacillus" title=" Lactobacillus"> Lactobacillus</a>, <a href="https://publications.waset.org/abstracts/search?q=post-harvest" title=" post-harvest"> post-harvest</a> </p> <a href="https://publications.waset.org/abstracts/121225/post-harvest-biopreservation-of-fruit-and-vegetables-with-application-of-lactobacillus-strains" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/121225.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">154</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9</span> Asymmetric Synthesis of β- and γ-Borylated Amines via Rh-Catalyzed Hydroboration of Allylamine Derivatives</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rukshani%20Wickrama-Arachchi">Rukshani Wickrama-Arachchi</a>, <a href="https://publications.waset.org/abstracts/search?q=Tanner%20Metz"> Tanner Metz</a>, <a href="https://publications.waset.org/abstracts/search?q=James%20M.%20Takacs"> James M.

Regioselective Rh-catalyzed asymmetric hydroboration of acyclic allylamines is used to synthesize amines bearing chiral β- and γ-boronic esters yields up to 70% with 98:2 enantioselectivity. The major enantiomeric outcome can be independent of starting alkene geometry, revealing that cis/trans-isomerization of alkene can occur before hydroboration.

Contamination surveys mostly focus on microbial contaminants or their secondary metabolites, mycotoxins. Chemical contaminants, particularly pesticide residues, however, are clearly substantial factors in the case of given condiments in the Capsicum family including spice paprika and chilli. To assess food safety and support the quality of the Hungaricum product spice paprika, the pesticide residue status of spice paprika and chilli is assessed on the basis of reported pesticide contamination cases and non-compliances in the Rapid Alert System for Food and Feed of the European Union since 1998. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=spice%20paprika" title="spice paprika">spice paprika</a>, <a href="https://publications.waset.org/abstracts/search?q=Capsicum" title=" Capsicum"> Capsicum</a>, <a href="https://publications.waset.org/abstracts/search?q=pesticide%20residues" title=" pesticide residues"> pesticide residues</a>, <a href="https://publications.waset.org/abstracts/search?q=RASFF" title=" RASFF"> RASFF</a> </p> <a href="https://publications.waset.org/abstracts/46930/food-safety-aspects-of-pesticide-residues-in-spice-paprika" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46930.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">394</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6</span> Efficient Ni(II)-Containing Layered Triple Hydroxide-Based Catalysts: Synthesis, Characterisation and Their Role in the Heck Reaction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gabor%20Varga">Gabor Varga</a>, <a href="https://publications.waset.org/abstracts/search?q=Krisztina%20Karadi"> Krisztina Karadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Zoltan%20Konya"> Zoltan Konya</a>, <a href="https://publications.waset.org/abstracts/search?q=Akos%20Kukovecz"> Akos Kukovecz</a>, <a href="https://publications.waset.org/abstracts/search?q=Pal%20Sipos"> Pal Sipos</a>, <a href="https://publications.waset.org/abstracts/search?q=Istvan%20Palinko"> Istvan Palinko</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nickel can efficiently replace palladium in the Heck, Suzuki and Negishi reactions. This study focuses on the synthesis and catalytic application of Ni(II)-containing layered double hydroxides (LDHs) and layered triple hydroxides (LTHs). Our goals were to incorporate Ni(II) ions among the layers of LDHs or LTHs, or binding it to their surface or building it into their layers in such a way that their catalytic activities are maintained or even increased. The LDHs and LTHs were prepared by the co-precipitation method using ethylene glycol as co-solvent. In several cases, post-synthetic modifications (e.g., thermal treatment) were performed. After optimizing the synthesis conditions, the composites displayed good crystallinity and were free of byproducts. The success of the syntheses and the post-synthetic modifications was confirmed by relevant characterization methods (XRD, SEM, SEM-EDX and combined IR techniques). Catalytic activities of the produced and well-characterized solids were investigated through the Heck reaction. The composites behaved as efficient, recyclable catalysts in the Heck reaction between 4-bromoanisole and styrene. Through varying the reaction parameters, we were able to obtain acceptable conversions under mild conditions. Our study highlights the possibility of the application of Ni(II)-containing composites as efficient catalysts in coupling reactions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=layered%20double%20hydroxide" title="layered double hydroxide">layered double hydroxide</a>, <a href="https://publications.waset.org/abstracts/search?q=layered%20triple%20hydroxide" title=" layered triple hydroxide"> layered triple hydroxide</a>, <a href="https://publications.waset.org/abstracts/search?q=heterogeneous%20catalysis" title=" heterogeneous catalysis"> heterogeneous catalysis</a>, <a href="https://publications.waset.org/abstracts/search?q=heck%20reaction" title=" heck reaction"> heck reaction</a> </p> <a href="https://publications.waset.org/abstracts/95373/efficient-niii-containing-layered-triple-hydroxide-based-catalysts-synthesis-characterisation-and-their-role-in-the-heck-reaction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95373.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">174</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5</span> Systematic Examination of Methods Supporting the Social Innovation Process</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mariann%20Veresne%20Somosi">Mariann Veresne Somosi</a>, <a href="https://publications.waset.org/abstracts/search?q=Zoltan%20Nagy"> Zoltan Nagy</a>, <a href="https://publications.waset.org/abstracts/search?q=Krisztina%20Varga"> Krisztina Varga</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Innovation is the key element of economic development and a key factor in social processes. Technical innovations can be identified as prerequisites and causes of social change and cannot be created without the renewal of society. The study of social innovation can be characterised as one of the significant research areas of our day. The study’s aim is to identify the process of social innovation, which can be defined by input, transformation, and output factors. This approach divides the social innovation process into three parts: situation analysis, implementation, follow-up. The methods associated with each stage of the process are illustrated by the chronological line of social innovation. In this study, we have sought to present methodologies that support long- and short-term decision-making that is easy to apply, have different complementary content, and are well visualised for different user groups. When applying the methods, the reference objects are different: county, district, settlement, specific organisation. The solution proposed by the study supports the development of a methodological combination adapted to different situations. Having reviewed metric and conceptualisation issues, we wanted to develop a methodological combination along with a change management logic suitable for structured support to the generation of social innovation in the case of a locality or a specific organisation. In addition to a theoretical summary, in the second part of the study, we want to give a non-exhaustive picture of the two counties located in the north-eastern part of Hungary through specific analyses and case descriptions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=factors%20of%20social%20innovation" title="factors of social innovation">factors of social innovation</a>, <a href="https://publications.waset.org/abstracts/search?q=methodological%20combination" title=" methodological combination"> methodological combination</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20innovation%20process" title=" social innovation process"> social innovation process</a>, <a href="https://publications.waset.org/abstracts/search?q=supporting%20decision-making" title=" supporting decision-making"> supporting decision-making</a> </p> <a href="https://publications.waset.org/abstracts/135702/systematic-examination-of-methods-supporting-the-social-innovation-process" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/135702.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">155</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4</span> Environmental and Toxicological Impacts of Glyphosate with Its Formulating Adjuvant</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=I.%20Sz%C3%A9k%C3%A1cs">I.

This phenomenon is demonstrated in the case of the herbicide active ingredient glyphosate. Due to its extensive application, this active ingredient was found in surface and ground water samples collected in Békés County, Hungary, in the concentration range of 0.54–0.98 ng/ml. The occurrence of glyphosate appeared to be somewhat higher at areas under intensive agriculture, industrial activities and public road services, but the compound was detected at areas under organic (ecological) farming or natural grasslands, indicating environmental mobility. Increased toxicity of the formulated herbicide product Roundup, compared to that of glyphosate was observed on the indicator aquatic organism Daphnia magna Straus. Acute LC50 values of Roundup and its formulating adjuvant Polyethoxylated Tallowamine (POEA) exceeded 20 and 3.1 mg/ml, respectively, while that of glyphosate (as isopropyl salt) was found to be substantially lower (690-900 mg/ml) showing good agreement with literature data. Cytotoxicity of Roundup, POEA and glyphosate has been determined on the neuroectodermal cell line, NE-4C measured both by cell viability test and holographic microscopy. Acute toxicity (LC50) of Roundup, POEA and glyphosate on NE-4C cells was found to be 0.013±0.002%, 0.017±0.009% and 6.46±2.25%, respectively (in equivalents of diluted Roundup solution), corresponding to 0.022±0.003 and 53.1±18.5 mg/ml for POEA and glyphosate, respectively, indicating no statistical difference between Roundup and POEA and 2.5 orders of magnitude difference between these and glyphosate. The same order of cellular toxicity seen in average cell area has been indicated under quantitative cell visualization. The results indicate that toxicity of the formulated herbicide is caused by the formulating agent, but in some parameters toxicological synergy occurs between POEA and glyphosate. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=glyphosate" title="glyphosate">glyphosate</a>, <a href="https://publications.waset.org/abstracts/search?q=polyethoxylated%20tallowamine" title=" polyethoxylated tallowamine"> polyethoxylated tallowamine</a>, <a href="https://publications.waset.org/abstracts/search?q=Roundup" title=" Roundup"> Roundup</a>, <a href="https://publications.waset.org/abstracts/search?q=combined%20aquatic%20and%20cellular%20toxicity" title=" combined aquatic and cellular toxicity"> combined aquatic and cellular toxicity</a>, <a href="https://publications.waset.org/abstracts/search?q=synergy" title=" synergy"> synergy</a> </p> <a href="https://publications.waset.org/abstracts/6041/environmental-and-toxicological-impacts-of-glyphosate-with-its-formulating-adjuvant" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6041.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">318</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3</span> Seismic Inversion for Geothermal Exploration</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=E.%20N.%20Masri">E.

In this study, we present rock physical attributes obtained from 3D pre-stack seismic data and well logs collected in a study area of the NW part of Pannonian Basin where the geothermal reservoir is located in the fractured zones of Triassic basement and it was hit by three productive-injection well pairs. The holes were planned very successfully based on the conventional 3D migrated stack volume prior to this study. Subsequently, the available geophysical-geological datasets provided a great opportunity to test modern inversion procedures in the same area. In this presentation, we provide a summary of the theory and application of the most promising seismic inversion techniques from the viewpoint of geothermal exploration. We demonstrate P- and S-wave impedance, as well as the velocity (Vp and Vs), the density, and the Vp/Vs ratio attribute volumes calculated from the seismic and well-logging data sets. After a detailed discussion, we conclude that P-wave impedance and Vp/Vp ratio are the most helpful parameters for lithology discrimination in the study area. They detect the hot water saturated fracture zone very well thus they can be very useful in mapping the investigated reservoir. Integrated interpretation of all the obtained rock-physical parameters is essential. We are extending the above discussed pre-stack seismic tools by studying the possibilities of Elastic Impedance Inversion (EII) for geothermal exploration. That procedure provides two other useful rock-physical properties, the compressibility and the rigidity (Lamé parameters). Results of those newly created elastic parameters will also be demonstrated in the presentation. Geothermal extraction is of great interest nowadays; and we can adopt several methods have been successfully applied in the hydrocarbon exploration for decades to discover new reservoirs and reduce drilling risk and cost. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fractured%20zone" title="fractured zone">fractured zone</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic" title=" seismic"> seismic</a>, <a href="https://publications.waset.org/abstracts/search?q=well-logging" title=" well-logging"> well-logging</a>, <a href="https://publications.waset.org/abstracts/search?q=inversion" title=" inversion"> inversion</a> </p> <a href="https://publications.waset.org/abstracts/155865/seismic-inversion-for-geothermal-exploration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155865.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">126</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2</span> A Cognitive Training Program in Learning Disability: A Program Evaluation and Follow-Up Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Krisztina%20Bohacs">Krisztina Bohacs</a>, <a href="https://publications.waset.org/abstracts/search?q=Klaudia%20Markus"> Klaudia Markus</a> </p> <p class="card-text"><strong>Abstract:</strong></p> To author’s best knowledge we are in absence of studies on cognitive program evaluation and we are certainly short of programs that prove to have high effect sizes with strong retention results. The purpose of our study was to investigate the effectiveness of a comprehensive cognitive training program, namely BrainRx. This cognitive rehabilitation program target and remediate seven core cognitive skills and related systems of sub-skills through repeated engagement in game-like mental procedures delivered one-on-one by a clinician, supplemented by digital training. A larger sample of children with learning disability were given pretest and post-test cognitive assessments. The experimental group completed a twenty-week cognitive training program in a BrainRx center. A matched control group received another twenty-week intervention with Feuerstein’s Instrumental Enrichment programs. A second matched control group did not receive training. As for pre- and post-test, we used a general intelligence test to assess IQ and a computer-based test battery for assessing cognition across the lifespan. Multiple regression analyses indicated that the experimental BrainRx treatment group had statistically significant higher outcomes in attention, working memory, processing speed, logic and reasoning, auditory processing, visual processing and long-term memory compared to the non-treatment control group with very large effect sizes. With the exception of logic and reasoning, the BrainRx treatment group realized significantly greater gains in six of the above given seven cognitive measures compared to the Feuerstein control group. Our one-year retention measures showed that all the cognitive training gains were above ninety percent with the greatest retention skills in visual processing, auditory processing, logic, and reasoning. The BrainRx program may be an effective tool to establish long-term cognitive changes in case of students with learning disabilities. Recommendations are made for treatment centers and special education institutions on the cognitive training of students with special needs. The importance of our study is that targeted, systematic, progressively loaded and intensive brain training approach may significantly change learning disabilities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cognitive%20rehabilitation%20training" title="cognitive rehabilitation training">cognitive rehabilitation training</a>, <a href="https://publications.waset.org/abstracts/search?q=cognitive%20skills" title=" cognitive skills"> cognitive skills</a>, <a href="https://publications.waset.org/abstracts/search?q=learning%20disability" title=" learning disability"> learning disability</a>, <a href="https://publications.waset.org/abstracts/search?q=permanent%20structural%20cognitive%20changes" title=" permanent structural cognitive changes"> permanent structural cognitive changes</a> </p> <a href="https://publications.waset.org/abstracts/95944/a-cognitive-training-program-in-learning-disability-a-program-evaluation-and-follow-up-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95944.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">202</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> Preliminary Study of the Hydrothermal Polymetallic Ore Deposit at the Karancs Mountain, North-East Hungary</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eszter%20Kulcsar">Eszter Kulcsar</a>, <a href="https://publications.waset.org/abstracts/search?q=Agnes%20Takacs"> Agnes Takacs</a>, <a href="https://publications.waset.org/abstracts/search?q=Gabriella%20B.%20Kiss"> Gabriella B.

The 14 Ma old andesitic-dacitic units are surrounded by Oligocene sedimentary units (sandstone, siltstone). The host rocks of the mineralisation are siliceous and/or argillaceous volcanic units, quartz veins, hydrothermal breccia, and strongly silicified vuggy rocks, found in the various altered volcanic units. The hydrothermal breccia consists of highly silicified vuggy quartz clasts in quartz matrix. The hydrothermal alteration of the host units shows structural control at the deeper levels. The main ore minerals are galena, pyrite, marcasite, sphalerite, hematite, magnetite, arsenopyrite, anglesite and argentite The mineralisation was first mentioned in 1944 and the first exploration took place between 1961 and 1962 in the area. The first ore geological studies were performed between 1984-1985. The exploration programme was limited only to surface sampling; no drilling programme was performed. Petrographical and preliminary fluid inclusion studies were performed on calcite samples from a galena-bearing vein. Despite the early discovery of the mineralisation, no detailed description is available, thus its size, characteristics, and origin have remained unknown. The aim of this study is to examine the mineralisation, describe the characteristics in detail and to test the possible gold content of the various quartz veins and breccias. Finally, we also investigate the potential relation of the hydrothermal mineralisation to the surrounding similar mineralisations with similar ages (e.g. W-Mátra Mountains in Hungary, Banska Bystrica, Banska Stiavnica in Slovakia) in order to place the mineralisation within the volcanic-hydrothermal evolution of the Miocene Inner Carpathian Belt. As first steps, the study includes field mapping, traditional petrological and ore microscopy; X-ray diffraction analysis; SEM-EDS and EMPA studies on ore minerals, to obtain mineral chemical information. Fluid inclusion petrography and microthermometry and micro-Raman-spectroscopy studies are also planned on quartz-hosted inclusions to investigate the physical and chemical properties of the ore-forming fluid. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=epithermal" title="epithermal">epithermal</a>, <a
